Is there anything that the Chinese can do that's not seen as a threat to the American people?
The definiton is probably not $country == "China" but a lot closer to $country != "America".
To stop being a one party dictatorship would be a start.
You didn't realize you just used exactly the same excuse that the US used to threaten other countries for dozens of years, did you?
Yes. And liberal democracy (the US in particular) is far from perfect. But it is objectively better than a one party dictatorship. It is also less "threatening" from an international relations perspective.
Objectively better than a one-party dictatorship? On what measures?
Great, finally it's not in the name of God and human rights
Wow you make it even more inspiring if you put it that way
